Siliciumverbindugen mit starken intramolekularen sterischen Wechselwirkungen, XV [1]. Cycloadditionsprodukte des Tetra-tert-butyldisilens / Silicon Compounds with Strong Intramolecular Steric Interactions, XV [1]. Cycloaddition Products of Tetra-tert-butyldisilene

The reaction of 1,1,2,2-tetra-tert-butyl-1,2- dihalodisilanes with alkali metals or metal naphthalenides leads to a complex reaction mixture from which one compound has been identified by its GC/mass spectrum as tetra-tert-butyldisilene (1). The constitution of 1 has been further confirmed by its cycloaddition products with benzil or 1,3-cyclohexadiene, respectively
